The F.A.B. Defense Front Polymer Flip-up Sight (FBS) is a robust and low-profile auxiliary front sight designed for versatility and precision. Compatible with any rear sight, it offers an exceptional optical advantage, making it a valuable addition to your setup. The sight pin elevation can be adjusted quickly and easily without the need for tools, ensuring you can make on-the-fly adjustments as needed. Its compatibility with any 1913 Picatinny rail makes it particularly suitable for M4, AR-15, and M-16 platforms.

Features:

• Low-profile design for minimal bulk
• Tool-free elevation adjustment for quick changes
• Compatible with any rear sight
• Mounts easily on 1913 Picatinny rails

The FBS can serve as either a primary or backup sight, and when paired with the matching FAB Defense RBS Rear Back-up Sight, it forms a precise optical tunnel that enhances aiming accuracy and target acquisition speed. Its low folded profile is designed to be smooth and inconspicuous, preventing snagging on gear or brush, while its durable materials ensure long-lasting performance.
